How Does The Cell Membrane Contribute To The Ability Of A Cell To Exists In A Changingenvironment And

Answers

Answer 1

Answer:

One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane. The lipid bilayer is selectively permeable to small, nonpolar substances. Proteins in the cell membrane include cell-surface markers, receptor proteins, enzymes, and transport proteins.

Describe how energy for the photosynthesis reaction is gained by plants?

Answers

Answer:

The chloroplasts that are on the leaves of plants trap the solar energy which is used along with carbon dioxide and water to make glucose and oxygen.

Explanation:

Sunlight provides the energy needed for photosynthesis to take place. In this process carbon dioxide and water are converted into oxygen (a waste product that is released back into the air) and glucose (the source of energy for the plant).

DNA is a double-stranded molecule i.e. it consists of two strands that are complementary to one another. According to the complementary base pairing rule, adenine base (A) will always hydrogen pair with Thymine base (T) i.e. A-T while Guanine base (G) will always hydrogen pair with Cytosine base (C) i.e. C-G.

Hence, based on the above explanation of complementary base pairing, the complementary pair of each DNA strand in this question are as follows;

Answer:  the last one. Brainliest??

Explanation:

Visible light and ultraviolet (UV) light are both forms of electromagnetic radiation, and waves of each travel at the same speed. Human eyes are unable to see UV light because it is not in the visible range of the electromagnetic spectrum. If the frequency of one UV light wave is twice that of a visible light wave, how will their wavelengths compare? A. The wavelength of the UV light wave will be half that of the visible light wave. B. The wavelength of the UV light wave will be twice that of the visible light wave. C. The wavelength of the UV light wave will be four times that of the visible light wave. D. The wavelength of the UV light wave will be the same as that of the visible light wave.

Answers

If the frequency of one UV light wave is twice that of a visible light wave, then the wavelength of the UV light wave will be half that of the visible light wave (Option A)

UV is a type of electromagnetic radiation that shows a range of wavelengths from 10 nanometers (nm) to 400 nm, whereas visible light shows a range of wavelengths from 400 to 700 nm (0.4 to 0.7 µm).

UV light exhibits a higher frequency and shorter wavelength than visible light.

The frequency is a unit measured in Hertz (Hz) which indicates the number of cycles (i.e., the waves) that pass a point in space during one sec.

The longest wavelength of visible light is the red color (700nm), whereas and the shortest visible wavelength is blue (400nm).

The frequency of the visible light ranges from 7.5×10¹⁴ Hz (blue color) to 4.3×10¹⁴ Hz (red color); whereas the frequency of UV light ranges from 800 terahertz (THz) to 30,000 THz.

Based on the information in the model, you might predict that there is more nitrogen in the soil now than before the industrial production of fertilizer began

Answers

Answer:

The answer is "True".

Explanation:

Nitrogen, potassium, or sodium fertilizers are examples of direct fertilizers. If nitrogen is being used as a nitrogen source in such a fertilizer, another synthetic method necessitates the use of natural gas - water. Sulfur, carbon, and industrial minerals are being used to make the phosphate element, that's why the given statement is true.

What are three ways that plants impact the cycle ?

Answers

Answer:

Carbondioxide gas, release oxygen and provide food.

Explanation:

Plant absorb carbondioxide gas, release oxygen and provide food to the animals are the was that plants impact the cycle. Plant absorb carbondioxide gas from the surrounding air in the presence of sunlight and absorb water from the soil. Both carbondioxide and water react with each other in leaves producing glucose and oxygen. Glucose is stored in different parts of plant body whereas some oxygen is used by the plant for respiration and the remaining is released in the atmosphere. The food produced in the plant can be eaten by the primary consumer for their growth and in that way the ecosystem moves in forward direction.

No Links Just Real Answers!!!!!!!!Develop a Model to Show the Release or Absorption of Energy from a Chemical Reaction SystemIn this project, you will develop a model of a chemical reaction that either releases energy or absorbs energy. Whether a reaction releases or absorbs energy depends on the overall difference in the bond energies of the reactants and products. Your model should show the relationships between the parts of the system. These parts are the molecules and atoms that take part in the reaction. The model should also distinguish the reaction system from other systems.BackgroundAtoms are the basic units of the types of matter known as elements. Very few elements exist in nature as single atoms. Most elements exist as atoms joined together into compounds by chemical bonds. During a chemical reaction, bonds are broken, atoms are rearranged, and new substances with new bonds form. Energy must be absorbed in order to break bonds, and energy is released when bonds form.For any given compound, the amount of energy that will break its bonds and the amount released when the same bonds form are the same. For example, 1 mole of water molecules must absorb 1,840 kJ of energy for its bonds to break. And, when 1 mole of new water molecules form, the same amount of energy (1,840 kJ) is released. The amount of energy needed to break or form 1 mole of a certain type of bond is called bond energy.As a reaction proceeds, the total bond energy of the reaction system changes. The total change in the bond energy depends on two factors:1) the energy absorbed by the initial molecules (reactants) in order to break their bonds, and2) the energy released as the bonds in the molecules that result (products) form.For example, if breaking the reactants' bonds requires less energy than is released as the bonds of the products form, then the chemical reaction releases energy. This is what the graph on the left below shows. A chemical reaction that releases energy overall is called an exothermic reaction. If breaking the reactants' bonds requires more energy than is released as the bonds of the products form, then the chemical reaction absorbs energy. This is what the graph on the right below shows. A chemical reaction that absorbs energy overall is called an endothermic reaction.The graph on the left shows a reaction system whose bond energy decreases. The graph on the right shows a system whose bond energy increases. So, the overall difference in the bond energies of the reactants and products determines whether the system absorbs or releases energy overall.You will need to work with your teacher to develop your model. You can model either an exothermic reaction or an endothermic reaction. Materials needed should be readily available to you. After plans for your model are approved, you will need to build and use your model. This will enable you to determine how well your model works. You should then make changes, if necessary so that your model more accurately describes the chemical reaction system.Part I: Develop a Plan for Your Model (20 points)1. Research atoms, chemical bonds, chemical reactions, and molecules. As part of your research, find ways that other people have modeled chemical reactions. Summarize your research. Use your summary to develop a plan to create a model showing that the release or absorption of energy from a chemical reaction system depends on the changes in total bond energy. (13 points)2. Write a brief description of the project you will do.
